Appears to be coming from the passengers side , dripping off the oil pan onto the exhaust, not bad but tired of smelling it.. What things could it most likely be on that side?
It's an 02 Z06
Update: just cleaned it, tightened oil pan bolts, that wasn't it.. It's actually leaking on both sides, like something higher up in the middle at the back of the engine is leaking?

Oil level sensor is over on that side on the back of the oil pan Do you have headers? They have been known to fry the wires to the sensor and the sealing material where the wires go into the sensor..

could be the engine rear cover. That's what it ended up being on mine. One of the upper bolts was loose and the oil would drip down the back of the engine and drip out of the bell housing weep hole as well as an area where the starter attaches. PM me your cell number and I can send pictures to explain it better.
Oil Pressure Sensor is on the back side top of the engine behind the intake manifold. A bit more toward the drivers side than exactly centered.. Also known to leak oil when they begin to go bad.
I shined a light on it with the engine running, best I could tell it wasn't leaking
Here is a shot showing both sides. All of this oil was from a loose bolt on the upper part of the rear cover.
Looks like a good possibility, gonna take it to work one day this week, pull it over the pit where I can get a better look, are those rear cover bolts hard to get to, to tighten? What has to be removed to access them?

I did it myself in the garage over a weekend. Its a lot of work to get to a $60 part (rear cover with rear seal installed). All of this stuff, and the bell housing have to come out just to get to the rear cover. The local auto shop wanted $2500 to do the job.

I had a oil leak that was dripping from both sides of the rear of the oil pan. The first owner had tried three times to have the leak repaired to no success including changing the rear main seal as well as the upper oil pan gasket. I pulled the engine this spring to find the leak. I found the upper oil pan was not level across the back of the back. Took it to the machine shop and had it surfaced. No leaks or drips since reassembly. The pan was really warped bad causing the gasket not to seal at the rear corners. It was causing a terrible smell when stopped and also leaking on the garage floor Good luck with your repair.
I would make sure it was not the more "common" problem first. My OPS started leaking a couple years after the Dealership reinstalled my OPS under warranty. Apparently thus did not torque it properly. Two mechanics told me that I had a blown rear main seal and my Oil Pressure Gauge was still working. I found it hard to accept that it was the rear main seal at such a low mileage.
Turns out it was a SLOW leak from my OPS not being fully seated, but I could not see anything until I cut into the cowl to check/remove it (not everyone will agree that cutting the cowl best method, but it worked great for me and since this is my 3rd sensor to have problems, I saw it coming again down the road). This is what I found when I looked inside...
